Approach for Preventing Suicide on Ceiling Fan

Abstract

Suicide by hanging is very alarming in India quite a high number of hanging cases is reported every year. As per a report of the World Health Organization (WHO), 800 000 cases are reported every year. Most of the hanging cases are commonly suicidal. The objective of the project is to develop an approach to the prevention system. The proposed project system consists of a PIC 16f877a microcontroller, PIR sensor, flex sensor, GSM module, Buzzer and actuator. The software used is MPLAB IDE with Embedded c programming and Proteus 8 professional for simulation purposes. When the person tries to hang the flex sensor senses the set weight, if it’s more than the set point weight, the GSM sends the message to the particular guardians. An actuator or the motor attached to the fan rod will extend downwards and make the person touch the floor. Buzzer will start beep to give alert to the surroundings.
